**Taper** mesh quality criterion represents the ratio of the areas
|
|
of two triangles separated by a diagonal within a quadrilateral face.
|
|
|
|
::
|
|
|
|
**JA = 0.25 * (A1 + A2 + A3 + A4)**
|
|
**TAPER = MAX(|A1/JA - 1|, |A2/JA - 1|, |A3/JA - 1|, |A4/JA - 1|)**
|
|
|
|
*To apply the Taper quality criterion to your mesh:*
|
|
|
|
.. |img| image:: ../images/image36.png
|
|
|
|
#. Display your mesh in the viewer.
|
|
#. Choose **Controls > Face Controls > Taper** or click *"Taper"* button |img| in the toolbar.
|
|
|
|
|
|
Your mesh will be displayed in the viewer with its elements colored according to the applied mesh quality control criterion:

|
|
|
